OOMPOS ITION- -AP PLYING MECHANISM FOR MATCH-MACHINES.

SPECIFICATION forming part of Letters Patent No. 662,297, dated November 20, 1900.

Application filed July 23, 1898. Serial No. 686,671. (No model.)

, hereby declare that the following is a full,

clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a composition-applying mechanism embodying my invention, witha portion of the side of the chest or vat broken away. Fig. 2 is a detail enlarged view in elevation of the end portions of the composition scraper and strainer. Fig.

3 is a top plan view of one of such end portions, and Fig. 4 is a vertical cross-section of the scraper and strainer.

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention is to free or remove from the dipping composition or material used in the manufacture of matches pieces of wood or other foreign substance that may fall or get into the composition chest or vat, so that when the sticks or splints are dipped the formation of clean and perfect heads will be assured and a means of forming double headers obviated; and to this end said invention consists in the means employed, substantially as hereinafter specified.

The composition-holding vat or chest A, having the revolving, feeding, or applying roller 13, (shown in the drawings,) is of familiar construction and need not be specifically described, nor is it necessary to show and describe the means by which the roller B is revolved, which roller, partially submerged in the composition, takes the latter on its periphery upward into the path of the lower ends of match splints or sticks held in and moved along through the match-machine by a carrier C of well-known construction-that is, composed of a series of perforated plates hinged or pivoted together. The composition vat or chest A is heated to keep the composition contained therein hot and liquid by a heating-jacket A, which can be of any desired construction, but, as shown, is one like that shown and described in United States Patent No. 528,457, issued October so, 1894,

on the application of E. B. Beecher and J. P. Wright, having a cavity or recess to receive the vat or chest, with its sides in contact with those of the latter, so that the heat from the heating fluid contained within the jacket will be directly transmitted and applied to the composition-vat and its contents. The jacket is to be kept hot in the same manner as that set forth in said patentthat is, by passing a heating fluid, as steam or hot water, into and through its interior chamber.

In the absence of means to prevent it frag ments of splints or pieces of wood or other dirt that may fall into the composition in the vat are carried by the rollerinto the path of the splints as they are moved by the carrier C toand through the coating of composition on the roller B and either adhere to the splints with the composition the latter takes up or prevent the proper application of the composition, so that defective or imperfect matches result. If the particles of wood or other material adhere to the splints, they are objectionable either as spoiling their appearance or, if they be long enough to reach between two adjacent splints, they cause the formation of double-headers-that is, two matches whose heads are united. Such matches as these are a loss and sometimes ignite when being ejected from the carrier. For preventing injury to the matches from the presence of such foreign bodies in the composition in the vat I remove the same from the composition by passing the latter through a sieve or strainer after it has been scraped, as usual, from the roller at a point beyond that where the splints come into contact with the composition on the roller. The scraper shown consists of a bar D, that lies parallel with the axis of the roller, that is fastened at opposite ends by screws to lugs e and 6, respectively, on plates E and E, that are in the vat at opposite sides thereof, having, respectively, flanges e and e, that rest upon the top edges of the vat sides. screw E, passing through each flange e into the vat side, removably secures the plate in the vat. The rollerengaging edge of the scraper-bar is beveled off, and to enable double service to be gotten from said bar both A thumb- IOO edges thereof are beveled, so that by reversing it the two edges can be used in succession .v To enable adjustment of the scraper-bar relative tothe roller, the opening 6 in the flange e of each side plate E is elongated.

The sieve or strainer F shown, into which the composition passes from the scraper, is formed of woven or meshed wire thatis shaped in the form of a receptacle, the ends being composed of the two plates E and E, to which the wire fabric is attached,and the two sides and the bottom being formed by said fabric. The plates E and E are connected by several parallel rods c and a to which the screen is attached and by which it is supported. The mesh of the fabric is of such size as not to impede the free passage of the composition, but to prevent the passage of foreign substances large enough to be injurious to the match-heads. The strainer, having the form of a pocket-like receptacle with i-nclosing ends, extends, as shown, down into the composition-vat well below the top of the heating-jacket, so that it is in position to be kept hot by heat from the jacket and will extend down into the heated composition. With this construction and arrangement the composition scraped from the roller 13 and falling down within the strainer cannot come in contact with any cold or cool part of the latter, which by diminishing the heat of such composition would tend to cause it to become less liquid or harden, so that it would not pass freely through the strainer or would cling to the wires of the same. As is well known by those familiar with match-making, the composition in the vat usually fills the latter up to or near the level of the top of the heating-jacket, but is not allowed torise above such level, where it would not be sub jected to the fulldirect heat from the jacket. The strainer is extended well down into: the composition in the vat, so that the part into which the composition scraped from the roll B falls will be immersed in the composition in the vat and so be always kept hot by the surrounding heated composition and be kept always supplied with hot liquid composition, with which that falling from thescraper will mingle at once without growing hard or caking. Thisarrangementinsuresthat the composition within the interior of the strainer shall always be hot enough when it reaches.

theinner side of the strainer or sieve to pass freely through the meshes thereof into the body of the vat and to part easily with the sticks, chips, or other foreign materials which may be in it and will be held: back by the sieve or strainer.

The strainer can be of any other construction than that shown, provided it is reticu- V l'ated or perforated and so interposed in the It will be observed that such pieces of wood, &:c., as fall into the strainer are kept from entering the composition Where it is taken up by the roller and that when desired the strainer can be readily removed from the vat to permit the clearing from the strainer of whatever maybe accumulated in it. As the strainer is located so that it cooperates with the scraper-bar and does not itself act on or require any special part to act on the periphery of the roller, it is apparent that the operation of the roller in feeding out the composition is in no degree interferred with.

The strainer being in the form of a pocketlike receptacle, with both sides and ends adapted to inclose the strained-off sticks,

chips, or other foreign substance, will when it of the vat, a moving feeder for taki ngcomposition from the vat, means for removing the composition from the feeder, and a strainer in the form of a pocket, with one or more of its sides adapted: to permit the passage of the composition, while holding back sticks, pieces of sticks, or other foreign material, such strainer being arranged to extend well down into the vat to a point belowthe top of the heater, so as to project into: the composition when in the vat, substantially as and for the purpose described 2'.

pieces of sticks,or.other foreignmaterial'which "may be mingled with the composition within the strainer, substantially as and for thepuzrpose described. a
